ER Doctor Opens Fire at D.C. Gym Over Condo Mold Lawsuit

Clear Facts

• Dr. Matt Lambert, 55, an emergency room physician, killed one person and wounded four others at VIDA Fitness in Washington D.C. on Thursday morning before taking his own life.
• Lambert was involved in a seven-figure lawsuit against the Metropole Condominium Association over alleged water damage and black mold in his $1.1 million condo unit.
• Police responded within 30 seconds of the initial shooting; the suspect barricaded himself inside his seventh-floor apartment and was found dead after more than an hour of negotiations.

Washington, D.C. authorities have identified the gunman responsible for the deadly shooting at a Logan Circle gym as a board-certified emergency physician with a long-standing legal dispute against his condominium association.

Dr. Matt Lambert, 55, opened fire inside the ground-floor VIDA Fitness facility shortly before 8 a.m. One victim was killed and four others were hospitalized, one of whom remains in critical condition.

Police arrived within thirty seconds of the first shots. They later determined the attack was targeted.

“We believe the suspect walked into Vida to target somebody that he had been in active litigation with, over a condo issue,” D.C. Councilmember Brooke Pinto stated.

After the shootings, Lambert retreated to his seventh-floor unit at 1515 15th St. NW. He barricaded the door and exchanged gunfire with officers.

Authorities spent more than an hour attempting to negotiate with the suspect before hearing a single gunshot inside the apartment. Officers then entered and found Lambert deceased from a self-inflicted wound.

Court records show Lambert filed a seven-figure lawsuit against the Metropole Condominium Association in March 2025, claiming that building repairs caused water intrusion, mold growth, and significant damage to his residence.

An X account linked to the doctor posted detailed complaints about the conditions, including a message from Wednesday that read: “Two years of living in luxury (and the start of 6 months with no shower, dryer, HVAC, and cooking).”

Lambert’s professional website described him as a physician with more than two decades of clinical experience who also authored books, played music, and engaged in philanthropy while splitting time between the nation’s capital and West Virginia.

The incident triggered a large-scale law enforcement response throughout the neighborhood less than a mile from the White House. Nearby schools were placed on lockdown while officers secured the area.

One resident told reporters the scene felt “like a war zone,” with helicopters and police units flooding the streets.

D.C. Mayor Muriel Bowser confirmed the White House had been briefed and labeled the shooting a “senseless act of gun violence.”
